Make a product mockup image of a stainless tumbler

## Output structure

**Main prompt**

Stainless tumbler product mockup, isolated hero product, upright three-quarter view, complete silhouette visible, balanced centered composition, seamless neutral studio background, soft directional key light from upper left, controlled fill light from front right, subtle grounded shadow, brushed stainless-steel surface, visible fine horizontal grain, clean rim, realistic lid construction, accurate cylindrical proportions, restrained commercial product photography, natural reflections, sharp product edges, moderate depth of field

**Negative prompt**

Plastic appearance, ceramic appearance, visible dents, scratches, fingerprints, condensation, liquid spills, warped cylinder, uneven rim, broken lid, floating product, cropped product, excessive reflections, harsh glare, dramatic bokeh, cluttered background, extra objects, text, label, logo, watermark, duplicate tumbler, distorted geometry

**Parameters**

- Aspect ratio: `[RECOMMENDED: 4:5 — suitable for a portrait product listing or promotional placement; change it if the final placement is different]`
- Resolution: `[RECOMMENDED: 2048 × 2560 px — sufficient detail for a portrait mockup; the generation service may not offer this exact size]`
- Background: neutral light gray
- View: three-quarter product view
- Finish: brushed stainless steel
- Product details: `[FILL IN: tumbler shape and lid design]`

## Render direction

The product remains the visual anchor: stainless tumbler first, upright and fully visible, with no competing object. The three-quarter angle exposes the cylindrical body, rim, and lid because those surfaces establish the product’s form. Brushed steel appears through fine horizontal grain and controlled reflections rather than exaggerated gloss. The upper-left key light creates the main highlight along the body; the weaker front-right fill preserves the opposite contour without flattening it. A soft shadow directly beneath the tumbler grounds it on an invisible studio surface.

Keep the background neutral and uncluttered so the metal finish is readable. Use realistic proportions and physically plausible contact between the base and the surface. Avoid decorative claims or unspecified branding. The mockup should remain generic unless the missing product details are supplied.

This direction changes the request from a bare object description into a usable mockup by fixing the view, light, material behaviour, and presentation context. It does not add a brand, logo, capacity, colour, or functional claim.

## Exclusions

Plastic texture, ceramic texture, dents, scratches, fingerprints, condensation, spills, warped body, uneven rim, broken lid, floating object, cropped silhouette, duplicate product, extra props, clutter, harsh glare, blown highlights, excessive bokeh, distorted reflections, text, label, logo, watermark, decorative pattern, invented branding

## Continuity procedure

This request describes one mockup, so no multi-image continuity procedure is required. If additional views or variants are later generated, preserve the same product wording, brushed stainless-steel finish, neutral light-gray background, three-quarter orientation, upper-left key light, front-right fill, shadow direction, camera height, and framing. Settle those values in the first approved image and quote them unchanged in later prompts.

Text wording alone will not reliably reproduce the same tumbler. For a series, use a reference image if the service supports one; otherwise record and reuse a fixed seed if available. A reference input generally preserves identity better than a fixed seed, and a fixed seed is useful only while the prompt and relevant settings remain unchanged.

## Parameters and handoff

Use the parameters above without adding service-specific commands or engine names. The recommended portrait ratio and resolution assume a product listing or promotional mockup; change them if the image is intended for another placement.

1. **[FILL IN: tumbler shape and lid design]** — provide the physical form to depict, such as straight-sided or tapered body and the actual lid structure.
2. **[FILL IN: intended use or placement context]** — state whether the mockup is for a product listing, advertisement, packaging concept, or another use.
3. **[FILL IN: output aspect ratio or placement channel]** — provide the required format if it differs from the recommended portrait setup.

Choose one path: **1. Fill in these product details and I will revise the prompt; 2. finish with the recommended values as they stand; 3. change the mockup structure first.** Wait for the choice.
